FOOTWEAR CONSTRUCTION;

ap licatio filed m 7, 1927, Serial. No. 189,653. Renewed March 2a,1921?.

This invention relates to footwear construction, and has more particularreference to an improved shoe adapted for'use by persons sufi'ering fromvfallen arches, bunions and rheumatism.

I is a well known fact that invalids suffering fiom foot ailments aregenerally affected with more than one foot defect, and-that the defectsmost commonly known are fallen arches, and enlarged joints, known asbunions. 1 Persons with fet so deformed or persons suffering fromailments as above specified, are generally rheumatic, and in viewofthese facts, I have provided several improved fea- 1 tures ofconstruction which 'are intended to be embodied in one and the sameshoe.

The principal objects of my invention are,

broadly, to'provide an improved and simplified water-proof shoe soleconstruction as required by persons suffering from rheumatism,

to provide an improved means for readily building up the arch portion ofa shoe to suit the requirements of fallen arches, and to provide anextension on the toe cap stiffener of the shoe for bunion protection.

The sole construction embodies a double welt with a strip sealed aroundthe welt. of

the intermediate sole and the margin of said intermediate sole, thestrip being stitched and I so cemented in position and so arranged as togive a double sole constructed shoe with a single sole storm weltappearance. The construction, objects and advantages "of the inventionwill become more clearly apparent from the following description takenin connection with the accompanying drawings. p l J -'n the drawings,wherein like'reference characters indicate corresponding partsthroughout the several views,

Referring more in detail to the drawings,,

the present shoe broadly embodies an upper 5 of the usual form andpreferably lined as shown in Figure 3, said upper having the usual toecap 6 provided with a special form of toe cap box or stiffener 7, a soleconstruotion generally indicated at '8 of special construction, and aconventional form of heel 9. The sole construction embodies a main orouter leather sole 10, a main or outer sole welt 11, a light or thinintermediate or slip sole 12, a light or thin secondary or slip solewelt 13,an insole 14, cork or like filler strips 15 and 16 respectivelydisposed between the inner sole 14.- and intermediate sole 12 andbetween the intermediate sole 12 and the outer sole 10, and a sealing.or water proofing strip or ribbon 17 placed and secured around the edgesand over the margin of the intermediate sole 12 and the associated welt13, the sealing strip and upper being inseamed betwecnthe inner sole andthe welt 13, and the sealing strip 17 being further inseamed between themain welt 11 and the'intermediate sole 12. The welt 13 and intermediatesole 12 are secured together by stitching through and through at themargin of the latter as 1ndicated at 18, the stitching however notpassing through the sealing strip 17, and'the welt, 13, upper 5 andinner sole 14' are secured to-' gather by stitching as at 19 through theu ,106

perand the welt but only gently through t 'e inner sole, the stitchinging concealed at the under surfaoe ofthe inner sole suitably slittingthe latter in a well known manner as indicated at 20. In a like manner,the welt 11 is fastened upon the margin of the outer sole 10 bystitching through and through as at 21, and the welt 11, strip 17 andintermediate sole '12 are secured together by stitching as at 22 throughthe welt and strip 17 but only partly through the intermediate sole 12with the stitching concealed by slitting the underside of theintermediate sole in the well known manner indicated at 23. By inseamingthe upper and the strip 17 in the manner described, entrance of moistureis effectively prevented without the use of rub.- ber sealing strips orlifts.

The inner sole 14 is slit between its surfaces at the intermediate orarch portion thereof and from the inner edge of the same to a pointadjacent but inwardly of the outer edge of the same to provide a pocketgenerally indicated at24 above the stitching 19, and provided on theinner edge of the portion of the inner sole abbve this slit is anextension or .projection 25 that is shaped and directed upwardly tocontact with the adjacent portion of the upper 5 as shown in Figure 3.It

will thus be seen that the pocket 24 is perma nently open and thataccess maybe had to the same by lifting the extension 25, to facilitateremoval or insertionof suitable pads or inserts whereby the arch portionof the sole.

may be readily built up to suit requirements or accommodate the patientsdeformity. The extension 25 is an integral part of the relatively stifl'leather inner sole and lies atthe inner side of the arch of the foot toadditionally aid in supporting the arch and to.

maintain the proper and neat shape of the adjacent portlon of the upper.forms of inserts may be employed in the pocket 24, and one form thereofis illustrated in Figures 41 and 5 and consists of a crescentshapedpiece of leather 26 conforming to the shape of the pocket 24 as well astapering thinner from the transverse "center of the same toward its endsand outer edge as illustrated in Figure 5. Naturally, the number andform of inserts will be governed by the conditions met with, and theinserts may be changed from time to time to gradually accommodate thearch support to the changing conditions as the arch regains its propercondition.

Resilient steel shanks 27 and 28 are disposed centrally andlongitudinally of the intermediate sole 12, respectively upon the upperand lower surfaces of the latter, and these shanks are secured togetherby rivets 30 extending through the ends thereof and through theintermediate sole 12. 'By this specific arrangement of. a plurality ofspring steel shanks, the arch will be doubl' resiliently supported andthe usual leather s ank will be eliminated. Moreover, by reason of theheads of the rivets engaging the respective metal shanks, danger oftherivets pulling looseor Various pulling through a leather part isobviated img a durable construction is consequently 1a The toe cap boxor stiffener 7 comprises a body portion of the usual well known formconsisting of a piece of stifi" and suitably shaped leather skived thinat'the edges and having its lower marginal portion inturned for readyattachment as at 8. In accordance with the present invention, the bodyportion of thetoe cap stiffener 7 is formed with an integral rearwardextension at its inner side as at 32 of a length to extend rearwardlyalong side the big toe joint to effectively resist pulling strains uponthe upper such as would cause pressure upon such,joint and consequentpain in the event of bunion trouble or lasting the upper and insole, thesealing,

strip is placed around the shoe. The sealing strip and upper are nextinseamed and the light welt strip 13 is then attached thereto with theinner sole. The thin cork filling is then provided as usual to preparefor the intermediate or slip sole which is skived and grooved as shownin the generally well known manner. The intermediate sole is nextcemented in position, the welt 13 being sewed to the slipl sole 12, andthen they are trimmed to give t e required appearance. The sealing strip17 is next cemented over the edge and'the underside of the margin of theslip sole 3 and over the edge and upper surface of the welt 13, andlasted in position, thus forming a substantially water-proof seal. Thewelt 11 is then applied and strip 17 is inseamed and fastened bystitching through the slip sole and the welt 11, making the waterproofseal complete. The second cork filler strip 16-is then applied and theouter sole is then assembled to the structure in the usual way,completing the sole.

From the foregoing description it will be seen that the soleconstruction is light and of a minimum number of parts, and has 'adouble sole construction with the appearance of a single sole with astorm welt. Further, the sole construction is substantially weatherproof for the desired protection to rheumatic patients and to preventrapid deterioration foot at the arch for bracing purposes. This bandpreferably comprises a pair of flexible elastic strips or sections 35and ,36 having their outer ends stitched by the stitching at 19- againsttheunder side of the marginal portions of the inner sole 14 between thelatter and the adjacent attached edges of the upper 5, as indicated at37 in Figure 10. The inner edges or ends of the elastic strips or bandsections 35 and 36 are suitably reinforced and provided with eyelets 38for restriction'o'f a lace 39 whereby the band sections are adjustablyconnected for being readily drawn into snug engagement with the foot. Asthe band section 35 is disposed outwardly of the inner edge of theinsert 26 and outwardly of the extension 25, the band will furthereffectively retain the insert within the pocket 24 and at the same timewill brace the extension 25 in proper engagement with the foot.Obviously, this construction may be embodied in the shoe of Figures 1 to3 inclusive with little difficulty during the manufacture of the shoe,

As shown in Figure 11, the pocket 24 may be extended at its forward endas indicated at 40 for receiving a supplemental insert in position tosupport the metatarsal arch, the supplemental insert being of course ofproper form to iit the extended portion of the pocket.
